There are very good reasons developers aren't encouraged to study on the job. The biggest one I can think of (that is especially prevalent today) is that not all studying results in usable knowledge, at least in software development. Every verdict is effectively the new rules that lawyers will play by the second that it is made; you could lose the case for not knowing a specific verdict. Medical professionals practice an ancient field that has no interest in gung-ho, extraneous solutions to problems that have already been solved. Software development is one of the few fields where people working it think that learning some oddball, corner-case framework that got its start because the original developer didn't like the code style of some other oddball, corner-case framework is necessarily and always desired by an employer. Mediocrity is honestly what many customers need. They don't need developers of Herculean strength that can create software of unfathomable complexity, they need a patch to their billing system (or something similarly trivial).
